For all LoadRunner users who work with Citrix deployed applications, it is important to note that there have been major changes to the Citrix 7.x architecture which will directly impacts how LoadRunner scripts are created. One of the big changes is that Citrix 7.x no longer uses ICA files to connect to the server. Instead, the ICA information is generated on the fly and is only usable for a short period of time.  Additionally, with the addition of the Citrix Storefront, the login and published app selection is HTML only.

Working with Tables
Sometimes working with VTS tables isn’t very straight forward.  VTS provides you with a single table for data sharing. Don’t think of it as a database table, think of it more of an Excel table.  There is NO forced row integrity – keeping related data on the same row Read Entire Entry

NOTE:  You can have multiple instances of VTS running and being used during a test. These code samples are assuming you are using a single instance of VTS.  If you are using multiple instances, you’ll want to use the vtc functions and NOT the lrvtc functions!  Instances are c Read Entire Entry

Install
This is the easy part.  You can find the VTS setup executable under the “Additional Components” folder in the LoadRunner install directory.  It is a quick and easy setup that you can do using the default options.  You can install the VTS on the same server as the co Read Entire Entry

Advanced Topics in VTS – Part 4 For those of you who have been using LoadRunner for a while, you may have heard about the Virtual Table Server (VTS). This is a technology has been around since the early versions of LoadRunner. However, the original version of the tool was never officially supported by HPE. There was Read Entire Entry

Previously we looked at using DFE to help make scripts that utilize XML to make it more readable and easier to parameterize.  There is another way to use DFE, beyond making a script more readable.  Sometimes DFE may be required for the script to run properly.  Some applications use what is called GWT (Google Web Toolkit).  To use GWT DFE, first you need to identify when an application is using GWT.

There is the obvious way that LoadRunner recognizes GWT.  You’ll see the following message in the Error tab of the messag Read Entire Entry

DFE is short for Data Format Extension.  It is a feature added to LoadRunner back in version 11, but a lot of people don’t understand what it is and how it can help you.  In simple terms DFE allows for easier LoadRunner scripting by allowing us to decode and encode normally unreadable or formatted data that the may be sent between the client and the server.  A simple example would be converting a long XML request into a more readable format.  Another example would be converting an unreadable Base 64 request into something that Read Entire Entry

I was running a load test overnight (SOAK) for 10 hours. Something happened overnight, and the Controller machine locked up. I could not log into it or connect to it remotely. It  had to be rebooted. When it came back up, I tried to recollate the results for this test and launch LoadRunner Analysis. I received this error message:

I was then prompted to look at the error log. I got: Analysis Error log:

Introduction to C Macros
C macros aren’t  discussed a lot by HP LoadRunner users, yet they are at the core of the C programming language used in VUGen. They can provide flexibility and power that reduces script development and maintenance times. A good example would be where a function cannot be used to encapsulate reusable code blocks because something in the code block must be known at compile time instead of at run time. In this case, there would be a global variable accessed within the code block, but the name of the variable Read Entire Entry

Community License
Probably one of the biggest changes to the product is HP’s new “Community License Bundle”. This replaces the old “Instant-on License” where HP LoadRunner would work with 10 users for a limited amount of time. This new bundle includes 50 Vusers, but it excludes Vusers for the GUI (UFT integration), COM/DCOM, and template protocols. Template protocols include C, JAVA, JavaScript, VB and VB Script, C#/C++.NET and VB .NET Vuser (Visual Studio Add-in), Enterprise Java Beans (EJB), VB.NET Vuser (Visual Studi Read Entire Entry
